UNITED STATES THOMAS O. ADAMS, OF NEV FHILADELPH MANUFACTURING COMRQJBTY, OF NEW OHIO.

. CHIG, TO THE VJISE-MCCLUNG CHIC, A CORPORATION OF ADJUSTABLE BRUSH FOR 'iTA-CUUEE Application filed Getober 9,

To all whom it may concern:

to it known that l, THOMAS O. linens, a citizen of the United States, residing at New Philadelphia, in the county of Tuscarawas and State of Ohio, have invented a new and usetul Adjustable Brush for Vacuum Cleaners, of which the following is a specification.

This invention relates to brushes for suction cleaning nozzles and more particularly to an adjustable brush mounted upon the outside of the nozzle adjacent to the lip thereof, and arranged to be detached from the nozzle or moved out of engagement with the carpet or other surface to be cleaned.

The objects of the invention are to provide a cleaning nozzle with an unobstructed o 'iening, a brush being detachably mounted upon the outside of the nozzle adjacent to the lip thereof, and arranged to be easily and readily moved into inoperative position out 01' engagement with the carpet or sur- Face to be cleaned.

The above and other objects may be at tained by constructing the nozzle and brush as illustrated in the accompanying drawings, in which Figure 1 is a side elevation oi; a va sum cleaner, the nozzle portion being shown in section, the brush being located in the operative position;

F 2, a sectional view (it the nozzle showing the brush in the inoperative position;

Fig. 3, an inverted, perspective view of the nozzle with the brush detached;

Fig. 4, a sectional view of the brush, showing the means of attaching the same to the nozzle;

Fig. 5, an inverted, perspective view 01 an attachment nozzle showing the brush attached thereto;

Fig. 6, a detached, perspective view oi? the brush shown in Fig. and

l ig. 7, a sectional view of one of the brushes shown in'Figs. 5 and 6.

Similar numerals refer to similar parts throughout the figures of the drawings.

The cleaner shown in Figs. 1 to 4:, includes the motor casing 1, tan casing 2 and nozzle 8, mounted for to and fro movement upon the floor upon the front and rear casters 4 and 5 respectively, the handle bail 6 being pivotally connected to the motor casing and for the reception of an operating handle by 1922. Serial means ot which the cleaner may be manipulated upon the floor.

For the purpose of taking up "from a carpet, or other surface to be cleaned. thread, lint or similar loose material, it is desirable to provide the nozzle with a disturbing device, such as a brush, to engage and loosen the threads or other material from the surface being cleaned, such disturbing device being desirably located outside oi the nozzle in order that an unobstructed nozzle opening be provided The di turbing device illustrated in Figs. 1 to t inclusive of the drawings, comprises a straight brush 7 parallel with and in rear of he rear lip 8 of the mouth of the nozzle. This brush is mounted upon a tubular rod 9 carried upon brackets 10 mounted near each end portion of the nozzle, one of said brackets having a stud 1.1 and the other bracket having a similar stud 12 provided with a transverse pin 13, the extremities of which stand beyond opposite sides of the studs.

A coil spring la is located within one end oi? the tube 9 and arranged to engage the end or the stud 11 when the tube is inserted over said stud, as shown in Fig. i, the other end 01" the tube being notched upon diamet rically opposite sides, as shown at 15, to engage the extremities of the pin 13.

lVith this construction, the brush may be rigidly held in the operative position, as shown in Fig. 1, by engagement of the matches 15 with the extremities of the pin 13, or the brush may be reversed and held in the raised position, as shown in Fig. 2, the notches engaging the opposite ends of the pin 13. It for any reason it is LlGSlIEL to remove the brush from the nozzle, the same may be accomplished by pressing the brush longitudinallv toward the stud 11, compressing the spring .lt until the opposite end oi the tube 9 is released from the stud 12, when the entire brush may be detached from the nozzle.

In adjusting the brush to either of the positions shown in Figs. 1 or 2, it is only necessary to press the brush longitudina ly against the stud 11 until the notches 15 are disengaged from the stud 12, when the brush may be rotated upon its axis to the opposite position, the notches 15 being again engaged with the pin 13.

Referring now to the construction illustrated in Figs. 5 to 7 inclusive, an attachment nozzle for cleaning draperies, upholstoring and the like is illustrated at 16, an attaching plate 17 being connected to each end of the nozzle as by a screw 18, the ends or said attaching plate extending outward upon both sides of the nozzle.

Each of the plates 17 has an inwardly disposed stud 11 at one end and a similar stud 12 at the other end, provided with a transverse pin 13" extending diametricall through the stud and projecting outward upon opposite sides of the stud. Each of the brushes 7 is mounted upon a tube 9% one end of which contains a coil spring 1 arranged to engage the adjacent stud 11 the opposite end thereof being provided with diametrically opposite notches 15 arranged to engage the adjacent pin 13.

The operation of the brushes 7 a is the same as the operation of the brush 7 above de scribed, each brush being arranged to be held fixedly in the operative position as shown in Fig. 5, or in the inoperative posi tion, out of engagement with the surface to be cleaned. These brushes, the same as the brush 7, may be easily detached from the nozzle in the manner above described.

is pointed out that each of the brushes 7 has bristles extending from one end to a point slightly spaced from the opposite end and as the two brushes are located in reversed position with reference to each other. as best shown in Fig. 5, bristles are provided along the entire length of the mouth of the nozzle.
